One of the most famous and popular toys of the modern era will be part of an upcoming display at the Kruger Street Toy and Train Museum in Elm Grove.

Starting Sunday, Aug. 3, the museum will unveil a new exhibit on the toy, celebrating its 50th anniversary. Through Jay Horowitz and American Classic Toys, the museum will display the original molds for the Rubik’s Cube.

On Aug. 3, guests can meet Horowitz and hear stories about how he ended up with the toy’s tooling from Ideal Toys. He also will describe how the Rubik’s Cube helped him create his own toy, the Sudoku Cube.

Guests also can see the original tooling, the patents, vintage Cubes and promotional literature related to Rubik’s Cube. Guests also are encouraged to bring their own Rubik’s Cube from home and, if they can solve the cube for museum staff in under five minutes, their admission to the museum that day is free.

According to the museum, in January of 1975, architect and inventor Erno Rubik filed for a patent in his native Hungary for the now world-famous puzzle cube which bears his name.

It was originally meant as an instructional aid and not a toy.

It became a hit in Hungary and was eventually exhibited at the Nuremberg Toy Fair. Ideal Toys saw the potential and negotiated the rights to produce and sell the cube worldwide.

By January of 2024, Rubik’s Cube had sold more than 500 million copies worldwide. It was inducted into the National Toy Hall of Fame in 2014.

Plans for Aug. 3 are still being finalized. An up-to-the-minute schedule of events will be found at www.ToyAndTrain.com.
